ROOF-TILE-CUTTING APPARATUS.

Application filed June 19, 1912.

To all whom it may concern:

it known that 1, JOHN Pisn'rTA, citizen of Austria, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in ltoof-Tile-Cutting Apparatus, of which the following is a speciiication.

The present invention relates to improvements in tile making machines of that general character in which the tile is formed of clay or other plastic material and is forced in a continuous stream through a suitable die.

One of the objects of the invention is to provide a tile machine ofthis character which embodies novel features of construction whereby the continuous stream of clay which is forced through the die can be quickly and economically cut up into predetermined lengths.

A further object, of the invention is to provide a tile making machine of this character which is strong and durable in its construction, which will operate in a quick and effective manner to accomplish the desired result, and which will enable the tiles to be manufactured in large quantities at a comparatively small cost.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which.:

Figure 1 is a top plan view of a tile making machine constructed in accordance with the invention. Fig. 2 is a front elevation of the same. Fig. 8 is a transverse sectional view through the continuous strip of clay which is forced through the die. Fig. i is a ciagrammatic view showing the path followed by the cutting members which sever the strip of clay into predetermined lengths. Fig. 5 is a diagrammatic view showing the manner in which the clay strip is out, the waste portion of the strip being shown by shaded lines.

shown in full lines as moved downwardly into an operative position, and in dotted lines as swung upwardly into an inoperative position. Fig. 7 is a detail elevation of the hook cutting device and the support therefor.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, which serve to illustrate one possible embodiment of the invention, the numeral 1 designates the supporting framework as an entirety, the said supporting framework being preferably secured to the face of the die C. See Fig. 6. A longitudinal shaft 2 is suitably journaled upon the supporting frame 1, and is provided at the middle portion thereof with roller 3, the periphery of the roller being slightly greater than the length of the finished tile members. A lower roller 4 is journaled under the upper roller 3 and the continuous length of clay emerging from the die 0 passes between these rollers, from the back of the machine toward the front thereof. A series of idlers 5 are journaled upon the main frame on each side of the lower roller 4 and serve to support the clay strip as it is carried to the main roller 3 from the die and to carry. the severed clay strips away from the machine. The clap strip 6, which is shown in cross section by Fig. 3 is provided at the top thereof with a longitudinal rib 7, portions of this rib being removed before the clay strip reaches the main roller 3, by a mechanism to be hereinafter described. It will. be ob-' served, however, that the main roller 3 is provided in the periphery thereof with a recess 8 which is adapted to receive that portion of the rib or hook 7 which is not removed and remains upon the finished tile.

The longitudinal shaft 2 is provided at each end thereof with a disk 8, each of the said disks being provided with the peripheral grooves 9 and 10 (see Fig. 1). The peripheral groove 9 is formed with a cam portion 9 while the peripheral groove 10 is similarly formed with a cam portion 10 After the continuous clay strip which emerges from the die is passed between the main roller 3 and the corresponding lower roller 4, it"is out into proper lengths by means of cutting wires 11 which are carried by the forked frames 12, (see Fig. 2,) one of the cutting wires being arranged on each side of the clay strip and mechanism being provided for causing the cutting wires to simultaneously act upon the strip from opposite sides thereof to cut it off in a straight line or on a large arc, as may be desired.

Each of the forked frames 12 is pivotally connected at an intermediate point in its length as indicated at 13, to one end of an operating lever 14:, the opposite end of the said operating lever being pivoted to the main frame 1 at 15. These operating levers are provided with pins 16 which are received within the pe'rip ieral grooves 9 of the disks 8. It will also be observed that the end of each of the operating levers 1a is pivotally connected at 17 to an arm 18 projecting from a ring 19 which is loose upon an eccentric member 20. This eccentric member 20 is rigid with a pinion 21 which meshes with a gear 22 which is rigid with a shaft This shaft 23 is provided vith a lateral arm 24 which also carries a pin for engagement with the peripheral groove 10 of the disk 8. The main roller 3 is caused to rotate by reason of its frictional engagement with the clay strip 6, and this rotation of the main roller 3 serves to rotate the two disks 8. As these disks 8 rotate, the pins 16 of the operating lever 14; travel in the grooves 9, and when they reach the cam portions 9 of these grooves the forked frames 12 are moved inwardly toward each other and the cutting wires 11 caused to act upon the clay strip from opposite sides thereof. The pins 25 also travel in the peripheral grooves 10 of the disks 8, and when these pins reach the cam portions 10 of the said grooves, the shafts 23 are rocked and the gears 22 turned so as to impart a partial rotary movement to the eccentric 20 and operate through the ring 19 and arm 18 to swing the forked frames 12 about the pivots 13 and thereby control the path followed by the cutting wires 11. The various parts are so arranged and timed with relation to each other, that the cutting wires follow the path indicated diagrammatically by Fig. 4. When the cutting wires 11 enter the clay strip, they follow the paths indicated by dotted lines a, the inward movement of the cutting wires being caused by the operating levers 14L while the forward movement thereof in the direction of movement of the clay strip is caused by the arm 18 and eccentric cam 20. The forward movement of the cutting wires is exactly equal to the forward movement of the clay strip, so that the resultant cutof the clay strip is on the transverse line A. The two cutting wires 11 meet at the middle of the strip, and the cam or eccentric 20 then comes into action and causes the two cutting wires to move directly rearwardly along the paths indicated by dotted lines Z) 6. The cutting wires are then withdrawn from the clay strip in a diagonal direction indicated by the dotted lines 0 0, the forward movement of the cutting wires being exactly equal to the forward movement of the clay strip, so that the resultant cut is along the transverse line B. These two cuts A and B are shown diagrammatically by Fig. 5, the shaded portion between the two outs A. and B being the waste portion of the clay strip, or that part which is not utilized. By slightly adjusting the dififerent parts the exact nature of the cut obtained can be varied.

Any suitable or conventional form of hook cutting mechanism may be employed in connection with the invention, since the hook cutting mechanism constitutes no part of the invention itself. As illustrated, the hook cutting mechanism includes a longitudinal shaft 26 journaled upon the frame and proviced at one end thereof with a lateral arm 27, said arm 27 being provided with a pin 28 adapted to engage a cam portion 29 upon one of the disks 8. At a point over the clay strip the shaft 26 is formed with a pair of arms 30 which are pivotally connected to a vertically disposed fork 31 having the tines thereof connected by a cutting wire 32. An arm 33 projects upwardly from the fork 31 and is provided with a bolt 34: which slides in an inclined slot 35 in a support 36. The fork 31 is normally held upwardly in an inoperative position, although when the shaft 26 is rocked the said fork is thrown downwardly by the arms 30. In a similar manner, when the shaft is rocked in a reverse direction, the fork 31 is moved upwardly into an inoperative position. The portion of the rib 7 which is severed by the wire 32 is discharged laterally into a chute 37 and carried to one side of the machine. A. guide member 38 is shown as carried by the lower end of an L shaped lever 39 which is pivoted at 40 upon the support, the upper arm of the lever be ing substantially horizontally disposed and projecting over a lateral finger 41 upon the arm 33 of the hookcutting fork. A tension spring 42 normally swings the L shaped lever to throw the guide block 38 into the path of the rib 7 so as to deflect the portion thereof cut by the wire 32 into the chute 27. However, when the hook cutting fork 31 is lifted, the finger 41 engages the horizontal arm of the L shaped lever and swings the said lever against the action of the spring 42 so as to move the guide member 38 out of the path of the rib 7 and into an inoperative position. The various parts of this hook cutting mechanism are so timed that the cutting wire 32 is swung clownwardly at the proper intervals necessary to remove the desired portions of the rib 7 and permit each tile to emerge from the machine with the rib 7 extending only a portion of the length thereof.
